Think there are different methods per different Bridal Shops.
Here's White Link's (WL) Style -
10am - reach WL office & start make up process. 1st outfit is casual wear. Make up light pink & Hair style simple (i.e, braids or pony tail)
11am - Change into Qua, pony tails become braids & hair decorations where neccessary. Make up touch up.
12pm - Quick lunch at WL office (I help the couple tabao)
12.30pm plus - Change to Evening no. 1, change of hair style (curls) & make up to match gown.
1pm plus - change to Evening no. 2, same as above change hair style (curls pin up now) & make up.
2pm plus - change to Wedding Gown, more time is spent doing the hair & make up. more photographs taken for wedding gown.
4pm - start packing up to move out for 1 outdoor shoot. Bride changes to outdoor gown & make up change with hair do.
5pm - set off to location. Make up artist nvr follow. pictures taken & back to the studio to drop off photographer & collect remainding things (plus pay up nxt wedding package amt)
think usually will set off earlier than 5pm for outdoor shoots maybe around 4pm when the temp is not so hot. as my fren had a bintan location she left later for her Spore outdoor shoot.
Also note the make up for each different outfit is not wiped away, it's piled on top of each other so end of the day my fren had a difficult time removing all the make up !!
